To ALL'wHoM. IT MAY conocen;

Massachusetts, have inyenteda new-'and improvedCounting-Annehment for Thread-Winding Machines; and I do hereby declare that the following isa fnll and exact description thereof, reference being had to the 'annexed drawings,which male a part of this vspecification,'and to the letters and figures of rcferencejnarl'ied thereon.

. .My invention relates' to a connting-attachnient, which indicates, by the revolution ofa graduated dial or an index,=the numberof'layers of thread Wonnd upon' a spool or hobbin in thread-winding maehinesofa certain class, thevgeneral'constrnotion and arrangement ofywhieh inachines it is necessary for me to describe briefly, inasmnclras said connting-attachincnt is operated by` such winding-machines, and made a p art thereof.

I Be it known thatIWIL-LAM GROS/Empf Holyoke, in the county of Hampden, and Commonwealth of In the class of winding-nmchines to'whichniyivention is designed to be applied, the thread is drawn from s bobhin or reel by -theh'ot'ition of the' spoolupon which .it is t9 be wound, and is distributedupon the spool in closcly-woundlayersbya.threadghide,whichl has a traverse motion, the layers of thread running alternately from oneend ofthe spool to the other. .'The traverse motion is imparted to the Athread-guide by means o' a revolving screw-shaft, having right and left-handed screw-threads ent upon corresponding portions of it, between its bearings.A These screw-threads work intof-segnients'of nuts, of brass orvo't-her soft metal, each segment being -ditte'd to'engage with one of the reversed sc rew-Athreladsupon the shaft. The segments' are rigidly connectedby setvlscrew'sl'iand arms toa slidingshaft, in such a relative position that, when one segment is contact with the screw-shaft, the`otherwill'be disengaged, and' thus, byvbringi'ng'the segments alternately in contact with the revolvingiscrew-shaft, a travers'emotion-will beiimparted to the 'sliding shaft to which the segments of nuts are attached, and to th thread-guide, which is 'fastened toA 'the end of the sliding'shaft, and the guide can therefore be made to traverse fr omendjto endof thefspool which is being wound. When the thread has been wound up tooneshoulder of;` the SpOOLthc-operator, by annrrangement of a winch and levers, is enabled, by a slight motion of thohand, to dscngagc the segiilental nut, which has been controlling the motion of the thread-guide in one direction, and to bring the other segment in contact with the reversoscrew-thread, and thus cause the thread-.guide.toretrogradc and distributea layer of-thread n-p to the opposite shoulder ofthe spool, and this operation'is continued until the spool is full.. The'rclative speed of the screw-shaft and of the spool-spindle is capable of being regulated vso that the thread-guido will traverse at the precise rate of speed necessary to deposit the thread in closely-wound layers, whether'it is finer or eoarser. The spolis forced from the Spoolspindle, when woundlby t'hcpressn-re of a detaching-plate or finger, which is attached to a shaft operated by a draw-lever, under the control .o f the operator. The operation ofthe regstering-dial or index inthe said countingattaclinient is controlled, by the motion of the traversing-shaft of the winding-machine; and I also use the reciprocating motion of- 4the rodwhich operates thedetaching-finger, 'to liberate the dial .or index, after a spool has been wound, so'that it is free tobe readjuste'd for thenext registering. My invention can, therefore, be readily applied to all thread-'winding machines in which a traverse motion of any of 'the operative parts can be used to'ilnpart motion toa connting-attachment or indicator.

In'` setting forth the'construction of my invention, will i'stvdescribe the dial-ease and diahand the parts immediately'. attachedthelneto; thenthevibrating-arm, and the parts connected with s'u'ch arm; and lastly, the parts'which-are'applied to the winding-machine directly', (the stud 'a and plateK,) to communicate motion to and'operatethe whole counting-attachment. v A

A dialcase, 'U-, having the front covered by the fra-ine and glass plate W', is supported above the winding machine, in fullkview of the operator, by the bracket U, fastened to`the rear side of the'winding-ma'chine' by dowel-pins U2U, anda Yscrew-bolt. The indicating-dial turns upon a spindle, o l, projecting from the back of 'the dial-case., lhe front end of the spindle is made ofiproper shape to-enterI the gectangnlarfopening, p, in the 'index'`.7x:, which is made fast upon the spindle, and set so as to point vertically upward, or'to 'the starting-'point of the graduation upon the dial, however the latter' may be sct. Teethlcfgare cut upon the edge of the dialplate,'being at least as many; in number as vthe layers-of thread to be wound upon the spools.'

Tqprgyent-the dial from malfing more than one revolution, and thereby disarranging the countingfattachment, one tooth is left blank,'so thatif the windingmachinery is operated after a pertain numbcrof .traverses of the thread-guide have-beenmade, the pawl which revolvesl the dial willwork inthe blank space of the omitted tooth, and will not further mcve the dial.` The hollow shaft of the dial-plate turns upon the spindle'ohand extends from the reverse side offthe dial to the shoulder a2 of the spindle, and a groove is formed inzit, at ki, in which n. cord, gl, iig. 13, attachedv to a tension-spring, q2, (or an equivalent weigh@ is wound, for restoring the dial to its pla-ce after'eachspool'is-removed from the machine. The lower end of the spring is fastened'to an eye, g4, set iu the-base of the winding-machine. -The dial is made to revolve-in the direction indicated by the'c'urved arrow, and to prevent it, when released, from revolving too far the opposite direction by the draught of the tension-spring, a pin, g, is inserted in the back of the dial-plate, which comes in contactwith the adjustable stop s, projecting into the dial-case through the slot t, in the side U6. i

T oideaden the. blow ofthe pin g upon the stop s, when thedial is released and turns suddenly back to place,

a p'ad of'icather, sl, is 'attached to the stop. Any wear of the parts may he compensated for by moving the;

stop s upward orA downward intheslot t, to a point where it will .check the reyolutiontof the vdial when thc index poi-nts to.the rst mark'of graduation, and lat this point the stop isv secured by the nut 83. The slot t is also inode of suliicien't length tallow the stop to be lowered to a point .where it will allow the first mark of graduation ou the dial to move the length ofone space past the index, when the latter pointsvertically upward, sothat the dial can be moved forward one space before the index. pointsto such first mark or starting-pointef the graduation, which adjustment-willbe employed when the number of layers of thread tov be wound isuneven.

The frame W, containing the-glass plateW, is fastened to the dial-case by the'screws u passing through the lugs u into the sides of the case. .-The-dial-plate thus set in the case,l and supported above the machine, is

As the 'nrm Nisconpta'ntly pressed towhrd the traversing-shaft 1);, ity-.the action of the spring el, the p lat'e b will be made 'tolbear continually against the end 'of the study, which is; of o ourse, traversing with the lrub-inwhich it is insertedz and will, therefore, traverse' and retrurverseialong 'theplate b,.a s long as th'e \vin'ding continues. When the end of the stud arrives A:it tho edge of the notch g :and enters it,` it'is `evident thatfth plateb Willmove towards the traversing-shaft as far as t-hedepthof .the notch Will-allow, 'and that,V when the-end'of 'the stud moves beyond the angle of the notch, it willbegin to press back thel plate 6,' and vcontinue to-moveitvbackuntil'uthe 'stud has passed out of and beyond the notch,l`\pvhen"the plate will havcresumed itsoi'iginal position. Thisoperation being repeated at everjr trarer'se ofthe stud, theplatefand' the upper part of the `vibrating-arm Zz' will have a slight reciprocating' motion to and fromtho'traversing-shnft. As the detentm'is independentofthe vibrating-arm, it-will'prevent the dial from"tn rningtbackward, ndrtake upanyavdditionnl motionjn the-directiomof the arrow. 'When the "stud z enters the notch in the pl-ate, and allows-the vibrating-arm to move townrds the left, the pnwl'c, attached `to the arm, willi-nove in the same diretion ,faxid the depth of the notch is made suiiicient to allow the' pawl to-move past one tootliof vvthe dial-plate, and 'bear .against the opposite side of it. As the stud meets the opposite 'side Vofthe notch, it presses'backthe'vibrnting-arm and the pawlc, which letteruilhtherefore, revolve the dial in the-'direction of thearew a' distance equal tothe space occupied byone tooth on the periphery of .the dial.- Withl each traverse motion of the threadguide'from one shoulder of the spool to the other, twill be seenithat the pawl c will take hold of a'nemt-ooth upon the dial, 'andcausfe the latter to revolve'a certain distance.' The graduation upon theface -of-the dial is made to correspond. with the length ofone forward movement of the dial, so'tha-t, at veach traverseA movement of the stud d, the index vnfill point to the vnext division line upon the dish I Instead of a4 dialrevoiving behindfn fixed index, asshown, I have 'constructed and arranged the indicating ports attached tothe dial-case U, in siich manner that the-index was made to revolve while the dial remained stntionerthe 'constructionva'nd operation of ,the last-described devicobeing substantially the sameasthat already set forth, v

It vWill beseeuthat'. the plate beanbe made long enough to'allow .spools of nn'ylength suitable for the machirreto be wound thereon., snd-the'layers of thread upon themto bejndicated, although, from the nsual'form of thcshoulders of spools, erich successive layer is slightly longer .than theone beneath it; and that very :short liesliotCStIyer o f .thread 'to he' 0und.'-v The plate is fastened 't-othe'nrrn the bolt'ff; wheh szcrews'rinto jit.:- To' ennblejthe-operzitor tosct the' p late and notch at the proper 4point jin the widthof the ru'ncliiine, a Aslot-is '.{ormedin theenlarged pirt,-, of the arm, along rvhieh slottheholtff istnovcd,` as maybe necessaryl'tohrng spools can also be wound andthe layers thereon registered, as the countingattachment will operate successfully .if the stud only Atraversesfrom one ledge ot` the notch completely tothe opposite edge, or a distance equal to lthe full width of the notch, the plate b being properly set upon -the vibrating-arm, and by making the other parts to correspond, the width of thenotch, as shown; might .be lessened.

Although the attachmentwill indicate if the stud enters and leaves the notch at any point in its traverse, it is desirable that the stud should meet the ang-leof the notch at about the middle point'ot` its movement, whichl may be eli'cctc'l by movingthe plate laterally upon the vibrating-arm to the proper point. In .winding very short ispools, which would require but-'a limited traverse of the thread-guide and stud,.it is desirable `to use aspoolf spindle, having u shoulder against which the end of the spool may press,v and having also wings or other'd'e'vices 'to'hold the spool in place against Athe shoulder, in order that every spool may occupy the same-position ,relativc'ly to thcplate '1), when the latteris properly adjusted upon'thevibrating-a/rni.

The attachment described is constructed vto register any number of layers of thread up to forty-four, and the number andsize of teeth upon the edge of the dial, and the graduation, may be readily varied so as to register a larger number, itidesir'ed. If aneven number of layers is to be wound upon the spool, the stop's, in theside of'the dial-case, willxbe set at such a point that the index will point to the irst mark of'graduation on the dial, when thelatter revolves back to place, after being released from the pawls. But if an uneven number of layers is to be wound, andthe iirst layer is begun at the'end ofthe spool next to the operator, the thread-v guide, which was left at .theinnerend of the last spool wound, must be drawn out to'the outer end of-the new spoolbefore-the winding begins, and in bringing it-to this point, the stud will 'pass 'theinotch iu the plate, and the. dial will be thus turned the distance of one of the graduated spaces, and will lindicate that one layer-has becniiP-Yoii'nid upon 1the spodl ,before the winding has -commencedf To obviate' any confusion or mistake of the.

operator from this false indication, the stop's is .se-t, in enses of-windingan uneven number of layers, at a'lp'iver pointin the vslot-t, so that thcvdial, when released, will step at a point where the index will point one space back of therst mark otv graduation, and when the winding actually commences, vthe number of layers wound will be correctly indicated. v v i i" It will be seen-that thecounting-attachment described iscoactivc with the thread-wiuding machine to which itis applied, and that the operator has only to glance occasionally' at tho dial toknow when `the required numiber of layers has been wound upon the spool, at whichv timc,'by drawing the handle the plate H is brought forward. against the end of the spool, yand removes it from the machine, and at the same time the curvcdplate K willalso be brought forward, and press back the arms of the pawl and detent',-and release the dia|,`which will then be' free, and will turn' back to its position at'l starting, being arrested at that 'point by thepin and stop before described. After theI spool is dislodged, and the dial lrestored to place, the handle I is released, and the curved plate K is retracted to its priginal position bythe action of the spring L. 1 It is well known thiit for the security of thepurehas'er of spooled thread oryarn, the number of yards upon each spool is generally stamped upon it, o'r in some way made evident?. In windingthe thread from a bobbin upon the spool, the only means which the operative has hitherto had for knowing when the required length has been wound upon the spool in Vmachines of the class described, has been by countingvand retaining in the mind the'number of-succcssive layers wound, which number, in the work of attending a complicated machine run-ning at high speed, the operator is liable-to forget oir mistake before the spool is fully wound. In such oase the operative may either wind too few layers upon the spool, and thereby defraud thepurchaser, and injure the reputation of the manufacturer, or will more probably wind on too mans',7 laye1is,and thus entail a loss'upon the manufacturer. In either case, the detriment to a manufacturer using 'many winding-machines' is very com siderable, 'and the actual losshas been found, in many cases, to be heavy, and to obviate it as much as possiblefrequent measurements of the lengths wound are resorted toiwith'ont any adequate relief from the liability to loss and damage. By the use of a counting-attachmentl constructed, applied, and operating substantially as described, the operator, being informedot` the number of layers cf any given gradeof thread necessary te make the required number of yards upon a spool,` hasonly to observe the dial occasionally, and see that the winding stops when the dial indicates that the required numberA of layers have been wound, thus beingfreed from the lifiicult and uncertain task of noting and remembering the number ot' layers wound, while the manufacturer *andthe purchaser are equally protected-from loss or dama-ge caused bythe mistake or forgetfulness of tbe Winder. i

What'I claim as new in the invention hcreinbefore described, and desire tosecure by Letters Patent, rs- 1. A releasing-plate or tripper, in combination withthe spool-removing mechanism of a thread-winding machine, as and forthe purpose set forth. i

2. The notched-adjustable`plate b, secured to the vibratingarm,lin combination with the traversing-stud a, substantially as described. A
